Important Information

Caution: The XRT30 Bass Section Cabinet weight is 192

pounds (87.1kg) and the High Frequency Column

weight is 82 pounds (37.20kg) net. It requires two or

more persons to safely handle each section.

1. It is very important that Loudspeaker Cables of adequate size

be used, to ensure that there will be no power loss or heating.

Cable size is specified in Gauge numbers or AWG (American

Wire Gauge). The smaller the Gauge number, the larger the

wire size:

If the Loudspeaker Cables are 25 feet (7.62m) or less, use at

least 18 Gauge (AWG) wire size or larger.

If the Loudspeaker Cables are 50 feet (38.1m) or less, use at

least 14 Gauge (AWG) wire size or larger.

If the Loudspeaker Cables are 100 feet (76.2m) or less, use at

least 12 Gauge (AWG) wire size or larger.

The Loudspeaker Connection Terminals can accept up to 12

Gauge (AWG) wire.

2. For additional connection information, refer to the owner’s

manual(s) for any component(s) connected to the XRT30

Loudspeaker.

3. The XRT30 has built-in speaker protection in the form of six

automatic resetting solid-state devices as part of the

crossover networks. Two protect the tweeters, one for the

midranges and three for the woofers. The characteristics of

this protection are that a certain amount of overdrive is

allowed but extended periods of overdrive will trigger

protection. If an obvious lack of high, mid or low frequencies

is noticed, the Loudspeaker Protection Device may have

activated. The protection devices will automatically reset

when the volume control is reduced significantly and kept low

until the output of the affected Loudspeaker Element returns

to normal.

4. When the XRT30 Loudspeaker System is driven by more than

one amplifier, the output levels of the different amplifiers

connected to the Loudspeaker System must be adjusted to

achieve a proper balance between the low, midrange and high

frequencies reproduced. This adjustment is best achieved

through the use of audio test equipment operated by a

qualified installer.

McIntosh Acoustic Engineers have refined the line source

Column Loudspeaker concept to provide superior quality

midrange and high frequency sound reproduction in a full

range system.

The High Fre-

quency Section

utilizes a patented

Column Design

with multiple four

inch Midrange

LD/HP

Magnetic

Circuit Design

Drivers and one

inch soft dome Tweeters. Refer to figure 1. Since the audio

power fed to a column is distributed among all the drivers,

each driver does not have to work as hard, resulting in

greater power handling capability and a dramatic reduction

in distortion. The Sound Waves from the Column produce

a Cylindrical Wave Front with a stable symmetrical hori-

zontal sound dispersion to minimize undesirable floor and

ceiling re-

flections

that could

detract from

a stable

sound im-

age. Refer

to figure 2.

In the illus-

tration the

Loudspeaker on the left side produces a Cylindrical Wave

Front and the Loudspeaker on the right side produces a

conventional Spherical Wave Front.

The Low Frequency Section of the System consists of

two 12 inch Woofers. They have a large magnet assembly

and long

cone ex-

cursions

with very

low levels

of har-

monic dis-

tortion and

frequency

response

down to

16Hz. Re-

fer to fig-

ure 3. The Woofer also incor-

porates McIntosh’s Patented

LD/HP

Magnetic Circuit De-

sign with shielding to greatly

reduce any external magnetic

field. Extensive investigating

and testing resulted in a new

design concept which utilizes

a pair of aluminum shorting

sleeves in the magnetic cir-

cuit. Refer to figure 4. The sleeves virtually eliminate the

negative influence of the fluctuating voice coil field on the

permanent magnet

field. This results in

lower distortion due

to more linear mag-

netic flux in the

voice coil gap. Re-

fer to figure 5. Ad-

ditional benefits are

less volume com-

pression due to im-

proved heat transfer

through the sleeves and a cooler operating voice coil. Both

measurements, as well as critical listening, reveal ten times

less distortion than previous designs. A good example of

this low distortion is incredible smoothness and clarity in

the reproduction of the human voice.

The Crossover Networks used in the XRT30 Loud-

speaker Sys-

tem are de-

signed to en-

sure an even

frequency re-

sponse over

the entire au-

dible range.

The Low Fre-

quency Cross-

over Network

is a Third Or-

der design uti-

lizing Capaci-

tors and In-

ductors with

high current

capacity. Refer to figure 6. There are three different types

of low loss (DCR) Inductors in the network, each one cho-

sen not to exhibit any core saturation even at high power

levels. This prevents the addition of distortion to the music

at low frequencies. The High Frequency Crossover Net-

work utilizes both

Second and Third

Order Crossover

Designs. Refer to

figure 7. It also uses

Capacitors and In-

ductors with high

current capacity.

The Capacitors

used include low

loss (ESR) Polypro-

pylene and Mylar

types. Both Cross-

over Networks also

utilize self resetting

high current Poly-

Switches to provide an extra measure of protection.

The enclosures are an important part of the XRT30

Loudspeaker System. The Bass Section Cabinet is con-

structed from 1

inch and 1-1/2 inch

thick MDF with

laminated hard-

woods and veneers.

Internally, the cabi-

net is reinforced

with multiple MDF

Cross-Bracing

Trusses all de-

signed to help in-

sure that the cabi-

net will not vibrate.

Refer to figure 8.

The High Fre-

quency Column

Section utilizes a

massive extruded

aluminum enclosure that houses the 30 four inch Midrange

and 25 one inch Tweeter Drivers. Refer to figure 9. It also

has multiple front

to back internal

braces to form a

dampened rigid

Column Struc-

ture. The

Column’s small

footprint allows for a variety of different placements in a

room.

Patented LD/HP Technology

The McIntosh Low Frequency and Midrange Loudspeaker

Elements feature the patented LD/HP Magnetic Circuit

Design. This design, when compared to conventional

Loudspeaker Elements, reduces distortion significantly. It

also increases power handling and efficiency.

•

Neodymium-Iron-Boron Alloy Magnets

The 30 four inch Midranges and 25 one inch Dome Tweet-

ers all use this Alloy. The Neodymium-Iron-Boron Alloy

has a high flux density per unit of volume and helps to

keep the Column weight to a minimum.

•

Shielded Magnetic Field

The XRT30 may be used in Home Theater Installations

near a television receiver or monitor without causing the

television image to degrade. McIntosh has designed

special shielding around the magnetic structure of the

XRT30 Loudspeaker Elements to prevent interference.

•

High Power Handling

The Loudspeaker Elements and Crossover Components of

the XRT30 are all chosen for use with powerful amplifiers

up to 1,200 watts.

•

Superior Imaging

Locating the Column of Tweeters between the two

Columns of Midranges helps to generate a symmetrical

horizontal polar response for superior imaging.

•

Versatile Operation and Placement

In additional to the regular connections, the XRT30 Loud-

speaker System provides separate connections for Bi-Am-

plification and Tri-Amplification hookups. The Crossover

Network has provisions to ensure the best performance

when the High Frequency Column is mounted in a wall.

•

Gold Plated Input Connectors

The XRT30 input connectors are gold plated for superior

corrosion resistance and high electrical conductivity.

Loudspeaker placement in a room can greatly affect

performance. The XRT30 Loudspeaker is designed for

both Music and Home Theater Systems. The optimal

method for selecting speaker locations includes the use of

a real time spectrum analyzer operated by an experienced

system installer. An uncompromising installation would

take into consideration the floor, wall and ceiling

coverings, the type and placement of furniture and can

even include the architectural design of the room and its

construction materials. In those instances where placement

in the room is fixed an enviromental equalizer may be

needed to restore proper musical balance.

Placement near a wall, corner, floor, ceiling or any in-

tersecting surfaces will reinforce some bass frequencies.

Which bass frequencies are boosted by placement in a par-

ticular location is dependant on the dimensions of the

room. Test the various Loudspeaker locations by playing

music with continuous bass, setting up the speakers and

listening to them from the main listening spot. Move the

Loudspeakers to an alternate location and repeat the listen-

ing, paying attention to how the bass qualities and re-

sponse levels change. Do not assume the loudest bass is

best; rather listen for booming (a lack of articulation), as

well as a balance over the whole spectrum, to assure the

bass will not drown out the other parts of the music. Ex-

periment with various Loudspeaker positions until the lo-

cations that sound best are found.

Locating Loudspeakers for use in Home Theater

In a Home Theater application, the placement of Left and

Right Front

Loudspeakers

can be limited

by such

considerations

as the size and

location of the

video monitor.

The locating

suggestions in

the “for use in a

Music System”

section below

can still be

helpful as a

starting place. Refer to figure 17.

Locating Loudspeakers for use in a Music System

When used in a Music System the distance between the

Loudspeakers

and the listener

to the

Loudspeakers

should form an

isosceles

triangle. If the

speakers are too

far apart relative

to the listener,

some imaging

can be lost.
